Abstract
Globally, porcine rotavirus is a leading cause of gastroenteritis in nursing and post-weaning piglets, as well as adult pigs. Between February 2015 and June 2016, 156 fecal samples were collected from pigs in the Northeastern part of Accra, Ghana, and screened for Group A rotavirus using the ProflowTM Kit. Here, we describe different extraction methods that were employed to recover high-quality RNA for downstream analysis, with emphasis on a novel hybrid extraction method. The hybrid approach with a kit and manual extraction method led to a 10-fold greater RNA yield versus the kit-based method alone. The new extraction method gave an average purity ratio (A260/A280) of 1.8, which was also significantly higher than that obtained solely from the manual or kit-based extraction methods. Our novel hybrid approach will be useful in the extraction of rotavirus from animal fecal samples, thus improving the yield of RNA for downstream analysis. © 2024 Wiley Periodicals LLC.
